K.GUSS A2 PCM2706 + ES9023 fever level audio DAC sound card decoder finished product with OTG headphone amplifier AMP board Description: With OTG function, USB power supply, you can also use external power supply SNR 112db, distortion -93db, direct output 2V RMS audio voltage, high-frequency no glitches, low-frequency full, good dive ES9023 internal negative pressure conversion, can output 2V (RMS) signal can be directly after the power amplifier, or preamp. Distortion: THD + N: <0.006% (RL = 10 kΩ) The ES9023 is a 24-bit stereo audio digital-to-analog converter (DAC) from ESS, with an integrated 2Vrms output driver. Using the industry's advanced SABER digital-analog conversion technology, this chip set the best sound quality, cost-effective in one, making it an ideal choice for digital-analog conversion. The ES9023 uses a patented HyperStream architecture and time domain jitter cancellation technology to achieve jitter-free recording quality with a dynamic range of 112dB. Because the integrated charge pump in the chip can generate negative voltage, ES9023 can directly output 2Vrms with reference to ground under the single power supply, eliminating the DC voltage isolation coupling capacitor. Moreover, the output amplitude can be less than 2Vrms level through the resistor according to actual needs. Switch machine noise can be fully inhibited. Dimensions (WxHxD):113*36MM Recommended Headphone Maximum Impedance: 251-300 Ohm Package Included: 1 x PCM2706 + ES9023 fever level audio DAC sound card / decoder / expansion card / daughter card
